  • 2. Santa Clara We will ...see how to implement an SOA solution using basic elements of an SOA infrastructure. ...demonstrate how to map enterprise SOA patterns, to a few real world and a few hypothetical business requirements. ...discuss SOA implementation details using products from the WSO2 SOA Platform.

  • 8. Santa Clara Usecase-1 (Business Scenario) Service client and service connected in P2P fashion in a production System. Backend service development team has decided to change the backend services. Secure the backend services. Change the service contracts. Introduce multiple services in place of a single service. Change Again ? Client/frontend developers PMs, Finance, HR etc.
